cardiovascular disease remains the leading cause of morbidity and mortality in the united states and europe. in recent years, the understanding that regenerative processes exist at the level of the myocardium, has placed stem cell research at center stage in cardiology. a stem cell is a cell that has the ability to divide (self replicate) for indefinite periods often throughout the life of the ...

background chronic allograft nephropathy(can)  is one of the most common causes of chronic and end stage renal disease. it  is defined with mainly tubular atrophy and  interstitial fibrosis and no evidence of any other etiology, or functional disorder that caused at least three months after transplantation . control of risk factors (htn,dm,hlp, …) and limiting  usage of calcineurin inhibitors o...

Despite the fact that a number of therapeutic modalities have shown promise in treatment spinal cord injury (SCI), focusing solely on one aspect recovery will not lead to successful and useful regeneration people. The current study targets an integrated approach neuroprotection rehabilitation strategies treat injury, increasing nerve functional through sensorimotor training cell transplantation...

Abstract A promising strategy to increase the numbers of hematopoietic stem cells (HSCs) for clinical applications, like cell transplantation, is offered by advanced in vitro culture systems. We developed artificial 3D bone marrow-like scaffolds made polydimethylsiloxane (PDMS) mimicking natural HSC niche . These PDMS combination with an optimized medium allow amplification high undifferentiate...

Bone marrow fibrosis is a hallmark of primary and post ET/PV myelofibrosis. To investigated the impact of replacement of the hematopoietic system in myelofibrosis patients by allogeneic stem cell transplantation on bone marrow fibrosis, we studied bone marrow fibrosis on bone marrow samples from 24 patients with myelofibrosis before and after dose-reduced conditioning followed by allogeneic ste...

background infertility is a serious social problem in advanced nations, with male factor in half of all cases of infertility. this study was conducted to determine the regenerative effect of bone marrow-derived stem cells in spermatogenesis of infertile hamster. methods twelve adult male hamsters were equally divided into azoospermic and control groups. busulfan was intraperitoneally used for i...

objective: nowadays, cord blood hematopoietic stem cells (hscs) are known as a valuable source for bone marrow transplantation but unfortunately their insufficient number is a limiting factor for using them in adult bone marrow transplantation. cord blood hcss expansion is an approach to overcome this problem, by inducing their self-renewal. tgf-b signaling pathway is a key inhibitory agent for...

Stem cell transplantation is the only curative treatment for a number of haematological and oncological diseases including lymphomas, leukaemias and several solid tumours. Recently the indications for this kind of treatment have been extended into other fields of internal medicine, e.g. autoimmune diseases. For stem cell transplantation it is necessary to have a graft consisting either of autol...
